Specification of Letters Patent.

Patented Sept. 17, 1912.

Application filed September 9, 1910, Serial No. 581,212. RenewedFebruary 21, 1912. Serial No. 679,187.

To all whom it may concern:

Be it known that I, JOHN OmsoN VAN CLnAvn, a citizen of the UnitedStates, residing at Sidney, in the county of Routt, State of Colorado,have invented certain new and useful Improvements in Hay- Stackers; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to hay loaders.

The principal object of the invention is to improve and simplify thegeneral construction of devices of this character.

A second object of the invention-is to so arrange the hoisting means ina hay loader provided with a pitching fork that themovement of this forkwill closely resemble the movement of an ordinary hay fork whenmanipulated by hand so that the initial raising of the hay isaccomplished at a relatively slow speed while the final or dischargemovement of the fork is at a relatively high speed.

A third object of the invention is to provide a novel arrangement ofhoisting means for such a fork wherein a greater power will be exertedduring the initial movement of the fork than at the end of the movementof said fork.

VVit-h the above and other objects in view the invention consists ingeneral of certain novel details of construction and combinations ofparts hereinafter fully de scribed, illustrated in the accompanyingdrawings, and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and Figure 1 is a side elevation of a hayloader constructed in accordance with this invention with the fork shownin its lowered position. Fig. 2 is a similar view showing the fork inits raised position. Fig. 3 is a vertical longitudinal section throughthe hay loader. Fig. 4 is a plan view of the loader. Fig. 5 is a detailperspective view of one of the pivots of the secondary frame forming apart of this invention. a

The loader comprises a main frame which includes a pair of longitudinalskids 10 by which the loader is supported on the ground so that it maybe transported from one place to another. At the rear end of these skidsare uprights 11 which are connected at their upper ends by a cross beam12 and the skids are held apart at their lower ends by a cross beam 18.Furthermore the parts are braced by the usual diagonal brace 14.Extending from the upper end of each of the members 11 downwardly andforwardly are which consists: of a pair of spaced triangular frames eachof which has a base member 19 and diagonal members 20, the latter havingtheir apical extremities connected to a perpendicular member 21. Themembers 19 are connected by a bar 22 whereon are fixed plates 23carrying pintles 24. which engage in the journal bearings 17. Thismember is arranged in the angle between the members 21 and 19. Thistriangular frame has its base vertical when the fork is lowered and inreferring to the different parts of said frame hereinafter it will beassumed that this is the posit-ion of the frame normally. The upper endsof the base members 19 are connected by a cross bar 25 while the lowerends are connected by a cross bar 26. The verticals 21 extend beyond theapex of the respective triangle and are connected by a cross bar 27. Theextremities of these perpendiculars are furthermore connected by a rod28.

The fork proper comprises transverse members 29 having fork teeth 30secured thereto and extending forwardly therefrom. These members 29 alsosupport a back rack 31. Attached to the fork are spaced arms 32 whichare pivoted upon the rod and these arms are braced to the rack 31 bybraces 33.

Extending upward from the members 15 are uprights 34 and diagonalbracing 35 eX- tends horizontally between said uprights and the members15. Connecting the upper end of said uprights 34 is a bar 36 which isprovided with suitable journals so that the bar is pivoted to rotatebetween said uprights. Extending rearwardly from the bar 36 is aseriesof fingers 37 forming a discharging platform and these fingers areconnected intermediate their ends by a mem her 38. Hinged to theextremities of the member 38 are supports 39 which pass through guides40 fixed to the members 11 and said supports 39 are secured in adjustedrelation in these guides by bolts 41. By this means the rear end of theplatform may be raised or lowered as desired. Se-

cured to the member 25 intermediate its ends and a second pulley 43 isse- 1 is a pulley 42 cured intermediate the ends of the member 27.Secured centrally of the cross bars 18 is a third pulley rod 28 andcentrally thereof is a fourth pulley 45. Secured intermediate the endsof the member 13 is a guide pulley 46. A cable 47 has one end secured tothe fork frame 29 and is led over the pulley 42 and pulley 43 around thepulley 44, over the pulley 45, and around the pulley 46 out of the sideof the device so that a draft animal may be attached to travel laterallyof the loader.

' In the operation of the device the hay gathered on the fork 30 islifted by stress upon thecable 47 At first the action is to rotate thetriangular secondary frame about its pivots until the pulleys 44, 45 and46 are brought into such alinement that the cable lies straightbetweenthe pulleys 44 and 46.- Then the triangular frame ceases torotate. During this part of the operation the frame.

has been lifted by the cross bar 26 which constitutes a stop member tolimit the movement of the arms 32 relative to the frame in onedirection. After thisinit-ial movement has been accomplished furtherstress upon the cable 47 will rot-ate the arms 32 about their pivotsuntil the fork braces 33 engage the member 36 which thus acts as a stopmember to limit the movement of the arms rearwardly. By reason of thepeculiar arrangement of the cable the initial movement is relativelyslow while the final movement is very rapid so that the hay is thrownviolently over the delivery platform toward In the returning of thedevice upon slack-' ing the cable the triangular frame first rotatesuntil the lower ends of the arms 15 are and brought to the rear of thecenter of gravity. The upper ends of these arms then move out strike thestop member 26 and the triangular frame and fork revolve together to theinitial position. There has thus been provided a simple and efficientdevice of the kind described and for the purpose specified.

It is obvious that many minor changes 44 and mounted on themay be madein the form and construction of this invention without departing fromthe material principles thereof. It is therefore desired to confine theinvention to the exact form herein shown and described but it is wishedto include all such as come within the scope of the appended claims.

Having thus described the invention what is claimed as new, is
